Ok, I have the latest dev build that came from OTA. But I was wondering what would be the benefit of replacing it with the latest nightly. I don't mind to use nightlies, especially having nickel as a stable option to use if something strange arises. But in order to optimize things I was wondering if some kind of automation exist.

I have koreader with KSM. Nikel doesn't update so frequently (who am I to have an opinion on this?) so next one I'll came to the forum to read before updating.
